Thank you very much. The iv_mtinfo struct is quite different from what I imagined, so my guess would not have worked.

I cannot get the application to link if I call GetTouchInfo() because it is missing from my libinkview.so (SDK 1.1a). Anyways, it doesn't matter because I can use dlopen/dlsym to make the call inside the if(type == EVT_MTSYNC) {} block for now. I will have to wait for an updated SDK before I can write code to call the function directly.
